Prenatal Vitamin D Boosts Children’s IQ — The Science Behind It

A growing body of research finds that pregnant women with sufficient vitamin D (25‑hydroxyvitamin D) levels tend to have children with better cognitive outcomes. Key findings include:

In the CANDLE cohort, each 10 ng/mL rise in maternal vitamin D was associated with a 1.17-point higher IQ in children aged 4–6. ([turn0search0]turn0search5])

The Odense cohort found early pregnancy or low cord blood vitamin D (<50 nmol/L) linked to a 2–4 point lower IQ, especially in boys. ([turn0search4]turn0search11])

The ECLIPSES study in Spain reported that deficient vitamin D in the first trimester (<30 nmol/L) predicted poorer cognitive and language scores at 40 days postpartum. ([turn0search6]turn0search9])

While results vary and randomized trials are still inconclusive, the evidence suggests vitamin D intake during pregnancy may support early brain development.
